' Application am March is, 1927. Serial No. 176,540.

My invention relates to improvements in stenclllng devices for electric bulbsand the ob ect of the invention 1s to provide a novel tool for use in stenciling electric bulbs,

whereby this operation may be expedited; a further object is 'to'devise such a tool which will constitute a combined stencil andholder for the bulbwhile it is being stenciled such that, when the bulb is simply inserted proper and within the tool,-it will be held in convenient positionfor stenciling.

- My invention consists in the construction and arrangement,; all ashereinafter more particularly described and illustrated in the accompanying drawings in. which f i Fig. 1 is a central verticalsection through my improved device showing a bulb'in position therein ready to be stenciled. I

Fig. 2 is a perspective view of my device,

a portion of a shank forminga handle there for being broken away.

In the drawings like, characters of refer ence indicate'corresponding parts in the two 1 the hand of the operatorand the device is;

held with the skirt directedupwardly as illustrated. i

A bulb 6 is simply inserted within the device and the shank 7 of the bulb seats within the cup 1. Infact this cup constitutes a receptacle within which the shank 7 of the bulb is:a snug :fitso that when the bulb is in position within the device it is supported therein by the engagement of the shank .7

within the cup 1. i l c The inclination of the walls of'the skirt 2 would be made to correspond to the; shape formed with a desired .ofthe bulb 6 being stenciled so thatthe skirt would follow accurately the contour of the bulb. In other Words a separate device ATEN ro icE wouldbe required for each particular shape and size of bulb. to be stenciled. a

' The design is stenciled upon the bulb by spraying the coloring matter through the perforated pattern 3 in the skirt 2and by making the mouth of the skirt flare out .wardly at it the likelihood of the sprayed coloringmatter getting over the top of the skirt and onto the portion of thebulb where it is not wanted is overcome and the sprayless care than would otherwise be possible. Fromthe foregoing it will be evident that I have devised an improved-device of the class described whereby the objects of my invention have been-attained.

invention without departing from the spirit thereof or the scopeofthe 'claimsand therefore the exact form shown is to be taken as illustrative only and not in a. limiting sense and I desire'that onlvlsuch limitations shall be placedthereonas are imposed by the prior art or are specifically set forth in'the,

appended claims.

What I'claim as mv invention is: I 1; A stencil device for electric bulbs comprising, a cylindrical cup-and a skirt extending from the mouth thereof, said skirt the wall thereof.

2. A stencil device for electric bulbs comprising, a cylindrical cup, a divergent skirt extending from themouth thereof, said skirt formedwith a desired perforated design in wardlyat its mouth. i

3. A stencil device for electric bulbs comprising, a cylindrical cup, a divergent skirt extending from the mouth thereof, said skirt 'ing maybe done with greater rapidity and;

Various modifications may be made in my "80 perforated design in I the wall thereof, andthe skirt flared out-' I formed-with a desired perforated design in the wall thereof, the skirt flared outwardly at its mouth, and a shaft extending'axially fromthe bottom of the cup. c
